johnniemo:Elevated greens make the ball come in flatter than a green at the same or lower elevation. Thus the roll out is considerably greater
This is exactly right and what it does is compromise any back spin you use. Basically, the shot arc is interrupted before it reachs full carry and comes in hot. BPB5 back tee is a good example, it's very hard to stick an approach (without wind help) because that green is so high up. Everything you throw up there rolls.
I like to max a club in situations like that. In other words, allow yourself a full swing without worrying about flying a pin, let it roll up. Worst case scenario you wind up with a decent, uphill putt, under the hole. :-)
p.s., @Jake-While it might seem like it's a little over the top to get so technical, it's how the pro's attack the game. You and I would probably have the same kind of RL round-laughing a lot and hacking away-but they don't. You have guys out there that can center a specific groove in their iron on the center of the ball they're so scientific. :-)
